200 Rack Safety and Precautions

Appendix D

Observe the following safety and handling precautions when you are installing 

equipment into the library’s rack: 

■

Ensure that the equipment has UL listing (listing by Underwriters’ 

Laboratories), CSA certification (certification by the Canadian Standards 

Association), and CE compliance (compliance with the European Council’s 

directives and standards).

■

Understand that the library does not supply power to the rack area. So 

ensure that the rack-mounted equipment has an adequate power source. 

Note

If you remove power from the library by using the library’s 

power switch, the rack-mounted equipment will remain powered 

on.

■

Follow the manufacturer’s guidelines to position, to support, and to fasten 

the equipment in the rack.

■

Locate the equipment so that it does not block or hinder any ventilation 

openings in the library’s rack area. For example, do not block library or 

drive exhaust areas, the electronic module exhaust area, perforated metal, 

or other similar ventilation.

■

Locate the equipment so that the library’s doors adequately clear the 

equipment when you close them. 

■

Install the equipment from the bottom of the rack to the top of the rack; HP 

recommends that you place the heaviest items near the bottom of the rack.

■

Ensure that any equipment that you place within the rack is adequately 

cooled. The library’s internal ambient temperature should not exceed the 

recommended operating temperature. Base cooling considerations upon 

the power dissipation within the rack space as well as upon the ambient 

room conditions that are external to the library. You must provide cooling 

for moderate power dissipation within the rack space.

■

Ensure that the equipment in the rack does not create an overcurrent 

condition, whether equipment is connected directly to the branch circuit or 

to a power distribution strip.

■

Ensure that the equipment in the rack has reliable earth ground, whether 

equipment is connected directly to the branch circuit or to a power 

distribution strip.
